CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When moving the shift lever into the M position using the transmission control switch, it is possible to switch the shift range position between "1" (first range) and "7" (seventh range). Shifting up "+" once raises one shift range position, and shifting down "-" lowers one shift range position.
